DEVELOPMENT OF A NEW COMBUSTION SYSTEM (MCA-JET) IN GASOLINE ENGINE

A new combustion system - called MCA-JET-has been developed to improve combustion under the low speed, low load conditions typical of urban driving. Engines with this new system incorparate a special "jet valve" in addition to the inlet and exhausts valves of the conventional combustion chamber, which directs air or a supper-lean mixture towards the spark plug, and induces a strong swirling flow in the cylinder. The combustion of lean mixtures, including those with exhaust gas recirculation cna be carried out rapidly and thus the fuel economy improved. Includes color photographs of flame propagation in combustion chamber. /SAE/
